We describe a subfringe integration interferometry for which the phase information is evaluated only from one interferogram.

叙述了次条纹积分干涉计量的原理，仅光载频干涉条纹图获全部位相信息。

The conoscopic interference patterns of crystals are calculated for any orientation biaxial crystal, which include information of isochromatic curve and isogyre.

针对任的双轴晶体,计算了完整的偏光干涉图,反映了相位分布决定等色线、振分布决定消光影的规律。
